After seeing the post on Greg Parigian's chopper sculpture, Bruce Parrish sent me some pics of the one he did for his father. It was based on and done when he finished his first build back in 1971. Bruce says, "It's 9.5" long and about 4" high at the sissy bar tip... and, yes, those are nails as well as washers, nuts and bolts, plus a few welding rods".
Bruce added, "Maybe I should go back to this form of art. Things happen way quicker".
